Research Strategy
Research Strategy - Automated Assembly Systems, Tooling and Fixturing
(1) Advanced Tooling and Fixturing
(2) Automated Assembly Systems
(3) Digital Factory
End Effector Tooling & Processes
Robotics Development & Implementation Systems Integration
Smart Jigs, Fixtures & Work Cells Sensing & Metrology Smart Factories
Gripping, Handling & Joining of Components
Identification, Location, Handling and Assembly of Component Structures
Final Assembly of Products
Informatics-Enabled Smart Factories
Business drivers: Improve global
competitiveness Dramatic reduction in
production cost Improve productivity Upskilling of labour Retaining capability to
manufacture complete products in the UK Improved quality and in-
service support
Product focus: High value, high complexity
products Variable volumes Trend towards product
customisation
Evolution: Product Process System

Shared System Model
Behaviour How will the system react to
disruption? How do we guide system
behaviour to achieve goals?
Capabilities What is the system topology? What can the whole system
do?
Products / Parts What happened to <PartY>?

Data Distribution Service
Data Distribution Services promote a decoupled, data-driven communication strategy Nodes publish and subscribe to
topics without concern for the origin/consumer node The topics and nodes form a
Shared System Context – a single canonical view of all data Resources need only take from
this Context what they require to make intelligent decisions

Robotic Assembly Scenario
Automatically apply and verify sealant application to multiple unique rib components Each rib unique – but not
immediately obvious to operator
Recipe-driven automation
Rib components to be assembled as part of larger structure Requires information about quality of
sealant to achieve tight tolerances
Automated cell, but decisions must be scrutinised if necessary Requires complete data logging
